Description
INFOID:0000000001731104
The yaw rate/side/decel G sensor detects the yaw rate/side/decel G affecting the vehicle, and transmits the
data to the ABS actuator and electric unit (control unit) as an analog voltage signal.

CAUTION:
• Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may
cause the yaw rate/side/decel G sensor system to indicate a malfunction. This is not a malfunction if
normal operation can be resumed after restarting the engine.
• If vehicle is on turn table at entrance to parking garage, or on other moving surface, VDC OFF indica-
tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn table or other moving surface, and start engine. Results will return to normal.
INSPECTION PROCEDURE
1.
CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E125 and yaw rate/side/decel G sensor
connector M108.
Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> Repair or replace as necessary.
